An Instructional Model for English Language Learners
to Reduce Cognitive, Culture, Learning, and Language Load
In this rapidly changing informational environment, where technological capabilities and social
opportunities far exceed the human capacity to fully engage, pedagogy is attempting to keep up
with the changes in an increasingly diverse classroom environment where learner experience,
skills, and modes of learning are increasingly disparate. While these conditions present a serious
challenge for educators and traditionally underserved populations, ELL (English Language
Learners) students are hardest hit. According to Meyer (2001), rather than simply dealing with
issues of cognitive load; culture load, language load and learning load also present instructional
considerations for the English language learner that must be addressed if learning is to “be
meaningful” (p. 229). A comprehensive instructional model is needed that creates a simple
replicable environment that will allow ELL students to participate in the process of rapidly
generating and acquiring underlying schema which can be cataloged in an organized culturally
relevant informational reservoir, thereby reducing cognitive load and accelerating their learning
process. In this paper, I will give a brief overview of the contribution of relevant learning
theories and methodologies to the current ELL environment and how each contributes (if at all)
to cognitive load; b) propose an instructional model that addresses the specific issues English
learners face; c) and give an example of the model in use.
Literature Review
Learning Theories, ELL and Cognitive Load
Behaviorism. B.F. Skinner’s behaviorist concepts and methods of instruction have been
used successfully for particular types of passive human learning where the focus is on
performance of a task manifesting in simple responses to stimuli (Ertmer and Newby, 1993).
AN INSTRUCTIONAL MODEL FOR ENGLISH LANGUAGE LEARNERS TO REDUCE LOAD 3
This theory ignores meaning, understanding, and underlying cognitive processes. Rather, tasks
are presented, rewards are implemented, and behavior is repeated until consistent performance is
achieved. Skinner, in his book Verbal Behavior, contended that language could be approached in
the same way that behaviorism dealt with other complex processes such as dancing—by using
the concept of chaining simple behaviors together (Driscoll, M.P., 2005, p. 64). Today, ELL
students are often taught vocabulary utilizing behaviorist methods of affirmation rewards for rote
memorization when the students successful pair a word with its definition. While this may not
unduly increase cognitive load in the early grades, the inadequacies of the method creates results
that will later be seen to contribute significantly to cognitive, language and learning load as
learning tasks increase in complexity.
Cognitivism. Unlike the behaviorists, the cognitivists did recognize the role of the
learner as an active agent in the learning process. The cognitivist also acknowledges the
existence and role of the mind (cognition) as it interacts with sensory information resulting from
the learner’s participation in the environment. Atkinson and Shiffin (1986) introduced memory
into the equation, proposing the flow of information from sensory input to sensory memory to
working/short-term and finally long-term memory (as cited in Driscoll, 2005, pp. 74-75). Key to
successful instructional design for the cognitivist is the role and importance of automaticity of
information, tasks and processes. This concept of automaticity is closely tied to cognitive load—
“gradually, they (tasks) become more automated, freeing cognitive resources for other activities”
(Sweller 1994). In their 1974 study, LaBerge and Samuels concluded that: “decoding words
should be so automatic…readers.. can concentrate their attention on comprehending the meaning
…” (as cited in Driscoll, 2005, p. 81). For the English learner, learning in a CIP environment
looks much the same as in a behaviorist classroom—days filled with extensive practice sessions

with corrective feedback (Ertmer and Newby, 1993, p. 58). The implications of this are many. Of
chief importance is the difficulty in achieving useful automaticity when the contextual and
cultural factors necessary to the assignment of meaning to words and concepts is absent from the
learning task. Students may have no known context in which to place the word and may
therefore be unable to retrieve and or use it when called to do so.
Constructivism. The objectivist view was losing ground and the passive role of the
individual was changing. In 1991, Jonassen clarified the nature of the shift to the individual
creating meaning from his/her experiences (p. 10). Constructivists cite instructional goals of
higher level reasoning, critical thinking, and cognitive flexibility (Driscoll, 2005, p. 402) and
instructional methodologies that include complex, real-world environments requiring that
learners develop problem solving skills assisted by extensive scaffolding. Because the learner is
steering his/her learning, the instructional goals are negotiated rather than imposed as
instructor/teacher objectives (Jonassen, 1991); but, from an ELL perspective this raises concerns
about the level of cognitive load. “Despite the alleged advantages of unguided environments…
cognitive load theory suggests that the free exploration of a highly complex environment may
generate a heavy working memory load that is detrimental to learning” (Kirscher, Sweller and
Clark, 2006). There must be a better solution.
Discussion
A New Instructional Model for ELL
In an effort to address the issues of cognitive, culture, language and learning load
experienced by English learners, and after a review of some of the existing instructional models,
I have constructed a preliminary model based on several assumptions which follow.
AN INSTRUCTIONAL MODEL FOR ENGLISH LANGUAGE LEARNERS TO REDUCE LOAD 5
Role of Technology: In most classrooms and teaching methodologies, the role of teacher
is shifting and technology is no longer optional. Krashen (1981) reminds us that “for more than a
decade English learners have been told that their role in the second language acquisition process
is a largely passive one…” (p. 228); and, the new instructional theories appear to give the student
a more active role. But, in truth there is little left to chance. Students may choose to watch a
video, push a key or type in a word. But, in most environments, the rest of the process is simply
responding to programming—the computer has replaced the teacher.
The Role of Dialogue. Meyer (2001) in her article on the Barriers to Meaningful
Instruction pointed out what Vygotsky believed to be of critical importance to a child’s language
development: “Through dialogue with adults, children learn to transfer their experiences from
the plane of physical action to that of words, creating ‘verbal thought’” (p. 228). In most
constructivist classrooms and teaching methodologies, Vygotsky’s dialogue is sadly absent.
Paulo Freire also spoke of the importance of dialogue in his book Pedagogy of the
Oppressed (2005): “Dialogue does not represent a somewhat false path....On the contrary,
dialogue characterizes an epistemological relationship. Thus, in this sense, dialogue is a way of
knowing…I engage in dialogue because I recognize the social…character of the process of
knowing. In this sense, dialogue presents itself as an indispensable component of the process of
both learning and knowing” (p. 17). Little time is available in the classroom for dialogue. Yet it
is the way we teach our children—the activity we choose when we interact with friends. A
holistic instructional theory should include planned, intentional dialogue supporting and/or
scaffolding the process; while also imparting meaning and guidance through shared discussion
throughout the learning process.

Role of the Learner: While I welcome the concept of the learner having an active role, I
am deeply concerned about the impact on the English learners unless they are more deeply
involved in the design process. No one knows better than an English learner what types of
problems are most difficult to understand and master. It is imperative that learners take an active
role in the design of the individual objects in the model.
Role of the Design Facilitator: There is no one better than an English learner who has
successfully bridged the gap to provide expertise and direction to the design process; thus,
providing the cultural context that is critical to the model being relevant, meaningful, and
effective.
Role of the Designer: Gagné’s model of instruction set about to garner the learner’s
attention, create a connection with prior knowledge, and then proceeded to enact a behaviorist
methodology paired with instructional guidance and feedback, expecting retention and transfer.
While Gangé does account for the existence of the whole person; like Bloom, he appears to
address the part(s) separately. The role of the designer is to create an integrated model that
addresses the English learners’ unique needs with cultural and contextual schema to reduce
cognitive, cultural and learning load, with a holistic mindset.
The Model. The model I propose is holistic and based upon the teacher/instructor,
cultural expert, and English learner working together to create learning objects that begin with
minimal structure. These can then be built into complex systems of thought and knowledge.
While we use a form of this in programming (objects, attributes, methods), this instructional
model reverses the process and makes a programming concept concrete. A library of basic
objects would be provided, and the user could discover the characteristics and how to use them
appropriately; changing attributes as scenarios change and become more complex. Each learner

defined object would be first be conceptualized with real world tools and involve a dialogue with
the instructor and fellow classmates about the attributes, constraints, and methodologies of the
object being developed prior to committing it to an electronic interface. Students would actively
participate, giving cognitive processes physical context. Below is an example of the process
applied to a problem one of my students discussed with me this week. We dialogued to clarify,
added context, and related the problem to her gaming culture.

Conclusion
English learners daily face many challenges. They live their lives as two people—one
who is Hispanic and speaks and thinks in Spanish at home with family and friends; and, the
other, who is American and expected to speak, act and think like it when at school. Our current
instructional design fails to address English learners’ unique needs, produces unnecessary
cognitive load, and fails to provide cultural context and adequate (schema) support for English
learners to be successful. A new model is needed if we hope to see every student given the
chance to be successful.
